No Intervention: Usual care
Usual care will include regularly scheduled visits with the clinical heart failure care team and medical therapy as prescribed by that team.
Experimental: Remote prescription for aerobic exercise
The exercise prescription will be created by an exercise physiologist after incorporating remotely collected data from a patient directed smartphone app assessing HF symptom severity, vital signs, weight, and blood sugar, and cardiac implant measures of physical activity, heart rate, heart failure volume status and heart rhythm, and Fitbit measures of physical activity.
Behavioral: Remote Cardiac Rehabilitation (CR)
Patients randomized to remote CR will be asked to use an app for cardiac rehabilitation a minimum of 3 times a week. Patients will be given an exercise prescription provided by a certified exercise physiologist.
The exercise prescription will change each week based on refreshed data from the prior week.
Instructional videos for each exercise are provided in the app. Patients will not be told to perform the exercise at a particular time. Instead they will be asked to complete a certain amount of exercise per week at whatever time is convenient for them. Patients randomized to remote CR will also receive App based reminders to take their medications, resources to guide healthy eating habits, and other behavioral health advice as is done as standard of care in both remote based and clinic based CR.
